Abstract: 672,571. Radiolocation. MARCONT'S WIRELESS TELEGRAPH CO., Ltd. Feb. 15, 1951 [May 25, 1950], No. 13207/50. Drawings to Specification. Class 40 (vii). In a frequency-modulated radar system of the beat-note-spectrum-analysing type (i.e. a system wherein the beat notes are heterodyned with a signal of continuously varying frequency from a local oscillator, the resultant signal being applied through a band-pass filter to a cathode-ray display unit the beam in which is deflected in synchronism with the local oscillator variations), and wherein the local oscillator frequency varies in accordance with a saw-tooth waveform, means are provided for incapacitating one or more circuits preceding the band-pass filter in the receiving part of the system during the flyback intervals of the saw-tooth waveform. By arranging the flyback interval to be sufficiently long to prevent oscillations excited in the band-pass filter at the end of a frequency excursion of the local oscillator from persisting until the commencement of the subsequent frequency excursion, false indications due to " ringing " of the bandpass filter may be obviated. In a preferred embodiment pulses synchronized with the flyback intervals of the local oscillator variation are derived and are applied to the automatic gain-control circuits in the radar receiver to prevent beat notes from being applied to the spectrum-analysing circuits during these intervals.

Title: Improvements relating to the manufacture of cross bottom bags
IPC: B31B150/00
Filed: 1952-05-26
Abstract: 708,697. Paper bags, making. HONSEL, C., [trading as MASCHINENBAU HONSEL & CO.]. May 26, 1952 [May 25, 1951], No. 13323/52. Class 94(2) In a machine for making crossed-bottom bags having arrangements for placing the flap 23, Fig. 3, over the flap 8, the flap 23, to be turned over in the direction of movement of the bag tube, is folded over by fingers moving faster than the tube and pressed down by a disc the peripheral speed of which is also faster than the tube motion. A continuous bag tube is severed into lengths at 6, 7, Fig. 1, after a stationary snout 2 has opened the end and shaped it against the fold cutter 3. Rollers 4, 5 flatten the opened-out cross-bottom and the bottom flap 8 is folded by the tongue 10 and cutter 11 on cylinders 9, 12 respectively. The cylinder 12 also carries the glue segment 13, fed from container 14a and roller 14, which applies the glue stripes 15, 16, 17, Fig. 3. The flap 8 is then pressed by roller 18 and guided by member 19 to be seized by the gripper 20 carried by the cylinder 22. The folding tongue 21 in cylinders 22, in co-operation with cutter 24, then folds the second flap 23 along the line 25, and thereafter the high-speed fingers 26 engage the back of the flap and fold it over into the recess 27 of the high-speed disc 28. The latter completes the folding and the finished bottom after pressing by roller 29 is delivered to the discharge table 30.

Title: Device for dispensing measured quantities of liquid
IPC: G01F11/00
Filed: 1936-05-11
Abstract: 466,984. Siphons. BAUMASCHINE AKT.-GES. May 11, 1936, No. 13332. Convention date, May 10, 1935. [Class 69 (i)] [Also in Group XVIII] In apparatus for dispensing measured quantities of liquids comprising a tank 1 adapted to be filled through a float controlled inlet 17 and discharged to a selected level through a siphon 2 which automatically interrupts the discharge when the liquid has fallen to a predetermined level, the float is located in an auxiliary tank communicating with the main tank and with the siphon, the auxiliary tank being emptied only when as a result of the lowering of the liquid level in the main tank an air inlet adjustable in height is exposed so as to interrupt the discharge through the siphon. This arrangement increases the accuracy of measurement by ensuring that the inlet valve will not open until the measured quantity has been discharged. The outflow of liquid is initiated by immorsing the siphon 2 by means of a hand lever 9 and continues until the liquid descends to the level of an air inlet nozzle 27 connected with the siphon by a tube 28 and carried by the arm 26 of an angularly adjustable shaft 25. As shown in Fig. 1, liquid from the siphon passes to the outlet 52 through an auxiliary tank 47 containing a float 48 controlling the inlet 17. The tank 47 is discharged by a siphon 53. In a modified form, Fig. 2, the liquid is discharged directly by the siphon 2 and the auxiliary tank 55 is located within the main tank and connected at the top with the siphon outlet by a pipe 62 and with the air inlet nozzle 27 by a pipe 60 and at the bottom with the main tank through a stand pipe 56. The discharge from the main tank causes a suction in the pipe 62 and top of the auxiliary tank and liquid is drawn in through the pipe 60 to maintain the level until the air inlet nozzle is exposed. In a further modification the stand pipe 56 passes to the upper part of the auxiliary tank which is discharged by a siphon pipe passing from the bottom of the auxiliary tank to the outlet of the siphon 2. The Specification as open to inspection under Sect. 91 comprises also modifications in which there is no auxiliary tank. One of these is similar to the form shown in Fig. 1 except that the outlet of the siphon forms the discharge outlet of the apparatus. In another modification, the tube 28 is dispensed with and the adjustable air inlet nozzle 27 is fitted to the open end of'the siphon. This subject-matter does not appear in the Specification as accepted.

Title: An improved method for preventing the separation of solid or semi-solid substances from liquid organic lubricants on the cylinder walls of internal combustion engines
IPC: F01M11/00
Filed: 1935-05-04
Abstract: A sulphur-containing lubricant for internal-combustion engines is produced by adding sulphur, e.g. 0,1 per cent, to lubricating oil, or by deliberately limiting the removal of sulphur from the oil during purification, or by converting certain constituents of the oil into elementary sulphur.ALSO:In order to prevent the deposition of solid or semi-solid substances, e.g. carbon, from liquid organic lubricants, the inner surfaces of the cylinder walls of internal combustion engines are modified by bringing them into contact with elementary sulphur at a temperature of from 100-about 350 DEG  C. Sulphur may be deposited on the walls, for example by electrolysis of solutions of sulphides, polysulphides, thiocyanates, thiosulphates, or sulphites, the deposition being mainly the result of electrophoresis, and the surface subjected to the elevated temperature, or an organic lubricant containing sulphur may be brought into contact with the walls at the elevated temperature. The elevated temperature required to effect the modification may be produced artificially or by the normal working of the engine, and the heating may be effected in conjunction with a supply of air.  When an organic lubricant containing sulphur is used this may be used continuously during the working of the engine or may be used only for a short time until the modification is effected. The sulphur-containing lubricant may be produced by adding sulphur, e.g. 0,1 per cent, to oil, by deliberately limiting the removal of sulphur from oil during purification, or by converting certain constituents of the oil into elementary sulphur.
